Why don't we hear.

Why don't we hear may well be titled why don't we listen.

First, what we should hear.
John 8:47 John 10:27 18:37b

John 8:29b Jesus speaking, "...for I always do those things that please Him." I think we get so lost in the have to do's that we forget it's not about commandments, it's about a covenant that He made with us, like marriage is supposed to be a covenant, not a contract, and we enter into this covenant with God because we love Him, because he first loved us. So we do what we do not out of obligation, but out of love we want to do everything to please Him. So if we're not starting out with that, we're off on the wrong foot already.
8:31b & 32 " If you abide (Literal meaning to continue in a permanent state, because He doesn't want us up and down, in and out He wants us by His side at all times, because He knows the enemy) in My word, you are my disciples indeed. "And you shall know the truth and the truth shall make you free." John 14:6 "I am the way, the truth and the life. No one comes to the Father except through Me."
Jesus states it pretty plainly, there's no way to hear what the Father has for each of us unless we're abiding, listening, and believing, all through Jesus and what He did for us, and "If anyone desires to come after me, let him deny himself, and take up his cross daily, and follow after Me." (Luke 9:23)
Reasons we don't hear?
John 8:34b "...whoever commits a sin is a slave of sin." And notice He doesn't say is a slave to that sin, but simply a slave to sin. Sin wants to take root and grow, sin isn't happy to just take a little and be settled, it must have more and more until it gets all of us, and then we find ourselves hardening our hearts and not hearing Him any more, but it usually happens a little bit at a time, compromise by compromise.
There's two fathers, if Christ abides in us, He is our Father, if He does not abide in us, the devil is our father. John 8:37-58
Good news in verse 36; " Therefore if the Son makes you free you shall be free indeed." Then Jesus in verse 37b says of those who want to kill Him, they that don't know Him "because My word has no place in you." Then 38 defines the different voices, and who's father we are; " I speak what I have seen with My Father, and you do what you have seen with your father." And in 41; "You do the deeds of your father." They claim their father is God, but Jesus replies in verse 42; "If God were your father you would love me." In 43; " Why do you not understand My speech" Because you are not able to listen to My word." 44: "You are of your father the devil, and the desires of your father you want to do." 45; "Because I tell you the truth you do not believe me." 47; "He who is of God hears God's words; therefore you do not hear, because you are not of God."
That's it, if we're not of Him, we won't hear Him, and if we are abiding in Him, we will hear Him, because we are His sheep, and we will not listen to the voice of a stranger. (John 10)
John 10:1-5 The good shepherd comes in and leads His sheep and the sheep hear His voice; and He calls His own sheep by name and leads them out. And when He brings out His own sheep, He goes before them; and the sheep follow Him, for they know His voice. Yet they will by no means follow a stranger, but will flee from him, for they do not know the voice of strangers.
Verse 9 says; "I am the door. If anyone enters by me, he will be saved..."
The devil only comes to kill, steal and destroy, but He has come to give life, and that they might have it more abundantly! Which father do we want to serve?
I love verse 16b of chapter 10, "and there will be one flock and one shepherd."
That's what I want to see, One Shepherd, the Good Shepherd, and one flock, that wonderful Body of Christ, that one that only listens to the voice of the Father! Wouldn't that be wonderful to see!
